The water dependence of each asset was assessed individually. In many cases, assets were clearly water dependent, such as groundwater bores, rivers and wetlands. In other cases, the water dependency of assets – such as the potential habitat of threatened species, ecological communities and regional ecosystems – was less clear. The Assessment team reviewed the available ecological knowledge and used spatial overlay to determine their water dependency. The water dependency of other assets – such as national parks, nature reserves or historical buildings – was assessed based on the presence of floodplains, wetlands or surface water features, shallow groundwater or other water-dependent assets within their spatial boundaries.

The water-dependent asset register for the Maranoa-Balonne-Condamine subregion (dated 26 June 2015; Mitchell et al., 2015a; Bioregional Assessment Programme, Dataset 1) described in companion product 1.3 (Mitchell et al., 2015b) was updated after product 1.3 was finalised. A review of the ecological knowledge used to determine the nature of the water dependency of the potential habitat of threatened species and communities identified an additional 17 ecological assets that were added to the water-dependent asset register for the Maranoa-Balonne-Condamine subregion. Consultation with Traditional Owners in the Maranoa-Balonne-Condamine subregion identified an additional 56 Indigenous assets that were considered to be water dependent. These additional assets have been added to an updated version of the water-dependent asset register (Bioregional Assessment Programme, Dataset 2; Bioregional Assessment Programme, 2017).
